After eight months of negotiations between Malian parties, the government and some armed groups signed an agreement on 15 May 2015 in Bamako. Fighting has resumed, however, in the north and centre of Mali. Crucially, the Azawad Movements Coalition (CMA) has still not signed the agreement. It initialled the text on the eve of the ceremony but demands further discussion before fully accepting it. An agreement without the signature of the main coalition opposing the government is of little value and will likely make disarmament impossible. The mediation team should establish a framework that would allow for further talks and Malian parties should return to the negotiating table at the earliest opportunity. The UN Security Council and its UN Multidimensional Integrated Stabilisation Mission in Mali (MINUSMA), backed by France, must take a stronger stance against violations of the ceasefire.
